We build a one-period general equilibrium model with money. Equilibrium exists, and fiat money has positive value, as long as the ratio of outside money to inside money is less than the gains to trade available at autarky. We show that the nominal effects of government fiscal and monetary policy...

This paper studies how government uses inflation tax to finance public goods affects the circulation of a national currency in a two-country search theoretic model. Each country consists of infinitely-lived private agents and a government. A representative agent obtains utility from the private...

This paper presents a model in which (1) fiat money has strictly positive value in the unique trembling hand equilibrium. This holds as each bank note is both: (a) a witness for the existence of some agent in the economy with debt, backed by collateral, and (b) the only matter that allows the...

A common belief among monetary theorists is that monetary equilibria are tenuous due to the intrinsic uselessness of fiat money (Wallace (1978)). In this article we argue that the tenuousness of monetary equilibria vanishes as soon as one introduces a small perturbation in an otherwise standard...

The 2008 crash has left all the established economic doctrines - equilibrium models, real business cycles, disequilibria models - in disarray. Part of the problem is due to Smith’s "veil of ignorance": individuals unknowingly pursue society’s interest and, as a result, have no clue as to the...

This study derives the monetary structure of transactions, the use of commodity or fiat money, endogenously from transaction costs in a segmented market general equilibrium model. Market segmentation means there are separate budget constraints for each transaction: Budgets balance in each...

In this paper, we articulate a vision for how widespread adoption of Digital Fiat Currency may affect the macroeconomic levers a nation has at its disposal to steady economic growth. We describe monetary (and certain fiscal) policy implications of a nation's choice to incorporate Digital Fiat...

This paper reviews what cryptocurrencies are, and it frames them within the context of historical monetary experiences and contemporary monetary economics. The paper argues that, as pure duciary private money, cryptocurrencies are a bubble without a fundamental value and that they will not...
